To all whom t may concern:

Be it known that ll, HARRY T. Goss, a citizen of the United States of America, and a resident of Rutherford, county of Bergen, and State of New Jersey, have invented certain ne'w and useful Improvements in rFWO-Section Doors, of which the following is a specication, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to doors and particularly to large, heavy doors, such as are provided with counterweights and hoisting mechanisms and are adapted for use on pier sheds, store houses and the like.

One object of my invention is to provide a simple and reliable door and operating mechanism of the aforesaid character that shall be particularly adapted for use where it is desirable to vprotect the opening from the weather when the door is' open.

position.

4Other objects and advantages of my invention Will be setforth hereinafter, and in order that my invention may be thoroughly understood, l will now proceed to describe the same in the following speciication and then point;l out the novel features thereof in appended claims.

Referring to the drawings, Figure 1 is a transverse `sectional elevation of a door structure embodying my invention, the door being shown in its closed A corresponding view of the same door in its open position is shown in Fig. 2.

Figs. 3 and 4 are plan views drawn to a `larger scale of portions of the door near its respective edges.

Fig. 5 is a front elevation of the door looking on the inside.

Detail views 0f thesame door are shown in sectional elevation on a larger scale in Figs. 6 and 7.

Like characters of yreference designate corresponding parts in all the figures.

For convenience l have referred to those portions of the door which are. adjacent. when the door is closed, to the lintel and to the sill of the opening, as the ends of the door, and to avoid confusion l have re- .ferred to the correspondingly4 located portions of each door section as its ends regardless of its shape.

rlhe structure illustrated comprises spaced of the door opening, a door having top and bottom sections 11 and 12, counterweights 13 therefor, and a door hoisting mechanism. As clearly shown in Fi .-3 and 4, each of the beams 10 has a box eam structure in which the counterweights 13 may operate and is provided with a channel-shaped section constituting a guideway 14 for the door rollers as hereinafter explained. The guide channel 14 is preferably flush with the surface of the door post in order not to interfere'with the opening and closing of the door. 'llhe upper section is longer than the lowerv section and is pivotally suspended from a transverse shaft 16, which is located near the lintel 17 of the door opening, by means of hangers 18.

Secured to the lower part of the upper section are channel strips or bars 19 which constitute guides for the bottom section 12 and are provided with pockets 21 near the top. The bottom section is equipped with rollers 2O which are arranged to run in the channels 14. Secured to the upper corners of the bottom section are brackets '22 carrying rollers 23 which run inthe channel bars 19.

The hoisting mechanism may be arranged in any suitable manner and for example may comprise a shaft 24 to which counterweight pocket sheaves 25 are secured, a

countershaft 26 carrying Aa hand chainl lows: assuming that the door is closed as shown in F ig. 1, when the hand chain 31 is actuated, the bottom section 12 is first raised until it overlaps the lower half of the upper section 11 'and the rollers 23 engage stops 32 at the top of the channel bars 19. A further actuation ofthe hand chain in the same direction causes the rollers 23 to enter the pockets 21. The upper section 11 is thendoor opening on the outside and is preferably provided with a transverse edge piece 33 in order that it'may shed water only at the corners.

The lintel 17 of the door opening is preferably providedI With an extension or flashing 34 in order to assist in preventing water -rom entering the door opening.

The action is reverse in lowering the door, a reverse movement of the hand chain serving to first lower the section 11 into a vertical plane and dropping the bottom section 12 into its closed position.

While I have shown what I consider a particularly desirable arrangement of box beam door posts, my invention is not limited to any specific arrangement and the doors may be utilized either singly or in groups in connection with buildings of various kinds. I have referred to the inside and outside of the door as related to the Jframe illustrated, but it is obvious that either side may be the outside and in fact the doors may be utilized in partitions where both are inside surfaces.

This application is a division of an application led by me on the 18th day of April, 1914, and given serial No. 832,671, and which I have assigned to the George H. Frothingham Company, a corporation of the State of New York.

What I claim is:

1. In combination with a doory frame, a door having a pivoted upper section, guideways secured to the respective edges of the upper section, stops in the guideways at point-s intermediate the length of the door section, a second section arranged to be guided at its upper end by said guideways, stationary guideways for guiding the lower section at its lowew` and. whereby the upper section is forced open and held in its open position by the lower section'when the lower section is hoisted.

2. In combination with adoor frame, a door pivotally supported near its upper end and adapted to swing outwardly to open, channel bars secured to the respective edges and having stops intermediate the door section, offset pockets opening into the respective channel bars adjacent, to the stops; a lower section having projections near its upper corners adapted to run in the channel beams as guides, and projections near its lower corners, stationary guide beams adapted to engage the projections at the lower corners of the lower sections, and hoisting means applied to the lower end of the lower section. 4

3. In combination with a door frame, a door pivotally supported near its upper end and adaptedV to swing outwardly to open, channel bars secured to the respective edges and having stops intermediate the door section, oiiset pockets opening into the respective channel bars adjacent to the stops; a lower section having projections near its lower corners, stationary guide beams adapted to engage the projections at the lowerY -witnesses`this 14th day of December, 1914.
